Fatal error: Failed opening required 'admin/config.php' in
/home/usr1/www.animeboards.net/htdocs/forums/categorylist.inc.php on line 2
You obviously have an error in the path you placed in the include statement. The path would not include the
http://www.animeboards.net URL.
Most likely the path is something along the lines of:
/home/usr1/htdocs/forums/categorylist.inc.php
The above path is just a guess based on the error you included!
